摘要
选取4个物种多样性指数对黄土丘陵区(安塞)主要的天然及人工群落物种多样性进行了研究,试图讨论植被恢复重建途径与物种多样性的关系。结果表明:处于植被自然恢复阶段的群落其物种丰富度指数、多样性指数、均匀度指数均在演替的第三阶段较高;人工灌木群落的多样性指数和丰富度指数都要大于人工草本群落,但是人工草本群落的均匀度指数要比人工灌木群落大;同样,天然植物群落比人工植物群落的均匀度指数小,但其物种丰富度、多样性指数均高于人为干预的人工植物群落。
According to the research on the natural and artificial communities by four indexes of species diversity in loess hilly region (Ansai), the purpose is to discuss the relationship between re-vegetation manner and species diversity. The results showed that natural plant communities have relatively high index of abundance , species diversity and evenness especially in third stage of succession;the species diversity and abundance index of artificial bush communities was higher than artificial grass communities,but evenness index was lower than that of grass communities;also,the species diversity and abundance index of natural plant communities was higher than artificial plant communities,at the same time,it has lower abundance index than that of artificial plant communities.
